<p class="Pa7"><span lang="EN-US">Knowledge of ixodids (hard ticks), as of well as their ability to transmit pathogens to their hosts, and in some cases to humans, is significantly important for the establishment of epidemiological public health programs and surveillance. With the purpose of identifying ixodids from wild mammals in the mountainous plateau of Santa Catarina, we examined ticks collected or received in the Laboratory of Parasitology and Parasitic Diseases of the Centre of Agroveterinary Sciences (CAV/UDESC) from 2001 to 2011. The ixodids were collected from wild animals that were subjected to the screening process of the Veterinary Clinic Hospital (HCV) of CAV and from dead animals found on state highways. Using specific dichotomous keys, we identified <em>Amblyomma aureolatum </em>collected from <em>Pseudalopex gymnocercus</em>, <em>Lycalopex gymnocercus</em>, <em>Leoparduspardalis</em>, <em>Cerdocyon thous</em>, <em>Leopardus tigrinus</em>, <em>Puma concolor, </em>and <em>Bufo </em>sp.; <em>A. dubitatum </em>collected from <em>Hydrochoerus hydrochoeris</em>; <em>A. rotundatum </em>from <em>Puma concolor </em>and <em>Bohtrops </em>sp.; <em>A. ovale </em>from <em>Bufo </em>sp.; and <em>Rhipicephalus microplus </em>from <em>Mazama gouazoubira</em>. A specimen of <em>A. longirostre </em>was identified in an urban area house at the municipality of Lages. <em>A. rotundatum </em>that was collected from <em>Bohtrops </em>sp. and <em>Puma concolor</em>, and <em>A. longirostre </em>that was found in the environment, are reported for the first time in the state of Santa Catarina, Brazil. </span></p>

During the study for biodiversity of wild mammals and their parasite and infectious agents, there have more risky to get natural hotspots due to global warming, huge number of domesticated animals and deficiency of pasture in Mongolia. Therefore, a major concern of researchers and rangers is survey to ascertain parasites of wild animals, particularly parasitism of migratory birds. We used to the study totally 224 feacal samples of wild animals, including 96 wild sheep, 101 ibex, 53 wild goose and 24 wild horse. The study results, found by helminth fauna of 7 genera such as Paramphistomum spp, Moniezia spp, Neoascaris sрp, Trichostrongylus spр, Nematodirus sрp, Haemonchus spp, Trichuris spp, belonging to 3 main classes of helminthes and Coccidia spp protozoa in feacal samples of mountain sheep and the 5 genera of helminthes such as Paramphistomum spp, Moniezia spp, Neoascaris sрp, Nematodirus sрp, Trichuris spp and protozoa Coccidia spp in feacal samples of ibex. The Paramphistomum spp have been found in mountain sheep and ibex for the first time in Mongolia.   The floatation method of feacal egg determination, shown that nematode infection of Ascaridae and Strongylidae in wild horses. The egg of Capillaria spp and oocyst of Eimeria spp in feces of swan goose and the eggs of two genera of nematode (Ascaridae spp, Capillaria spp) and oocyst of Eimeria spp in feces of grey goose were found in the study. The parasite fauna in feacal samples of certain wild host animals was considered by the prevalence of infection in Mongolia.    Зэрлэг амьтдын гельминтийн судалгаа Цаг агаарын дулаарал, мал сүргийн тооны өсөлт, бэлчээрийн хомсдол, хүний хүчин зүйл зэргийн улмаас мал, амьтны паразитын тархалт нэмэгдэж, улмаар зэрлэг амьтад гадна, дотор паразит, халдварт болон өвчнөөр өвчлөн байгалийн голомт үүсгэх явдал гарсаар байна.

Abstract Chlamydias are obligated intracellular Gram-negative bacteria, considered important zoonotic pathogens, broadly present in several bird species and responsible for economic losses in animal production. We analyzed the presence of Chlamydial species with zoonotic risk in farm animals in a highly biodiverse area and with great human circulation, the Argentine, Brazil and Paraguay tri-border area. We surveyed nine farms in an area and nasally swabbed a total of 62 animals. DNA was extracted and specific PCR was performed to identify chlamydial species. We detected Chlamydia spp . in 6.5% (4/62) of the animals tested, positive samples belonged to cattle and none of them showed symptoms of respiratory disease nor had been diagnose with reproductive diseases. Specific nested PCR confirmed two samples belonged to C. pecorum and two to C. psittaci . We report for the first time Chlamydia circulation with zoonotic risk in the region. Surveys in birds and wild mammals could give a better understanding to know what Chlamydial species are circulating in the wild interface. The zoonotic potential should be taking into account as farm workers and the surrounding population could be silent carriers or have respiratory diseases being underdiagnosed, and therefore should be considered in the differential diagnoses.

Angiostrongylus costaricensis is a nematode parasitic of rodents. Man may become infected by ingestion of the third stage larvae produced within the intermediate hosts, usually slugs from the family Veronicellidae. An epidemiological study carried out in a locality in southern Brazil (western Santa Catarina State) where these slugs are a crop pest and an important vector for A. costaricensis has documented for the first time the natural infection of Deroceras laeve with metastrongylid larvae. This small limacid slug is frequently found amid the folds of vegetable leaves and may be inadvertently ingested. Therefore D. laeve may have an important role in transmission of A. costaricensis to man.

AbstractHabitat modification may facilitate the emergence of novel pathogens, and the expansion of agricultural frontiers make domestic animals important sources of pathogen spillover to wild animals. We demonstrate for the first time that Plasmodium juxtanucleare, a widespread parasite from domestic chickens, naturally infects free-living passerines. We sampled 68 wild birds within and at the border of conservation units in central Brazil composed by Cerrado, a highly threatened biome. Seven out of 10 passerines captured in the limits of a protected area with a small farm were infected by P. juxtanucleare as was confirmed by sequencing a fragment of the parasite's cytochrome b. Blood smears from these positive passerines presented trophozoites, meronts and gametocytes compatible with P. juxtanucleare, meaning these birds are competent hosts for this parasite. After these intriguing results, we sampled 30 backyard chickens managed at the area where P. juxtanucleare-infected passerines were captured, revealing one chicken infected by the same parasite lineage. We sequenced the almost complete mitochondrial genome from all positive passerines, revealing that Brazilian and Asian parasites are closely related. P. juxtanucleare can be lethal to non-domestic hosts under captive and rehabilitation conditions, suggesting that this novel spillover may pose a real threat to wild birds.

Este artigo tem como objetivos identificar conflitos existentes entre criadores de caprinos da raça Moxotó e os predadores naturais dos seus animais, no município de Ibimirim, Pernambuco, bem como descrever as formas locais de prevenção aos ataques e suas implicações para conservação de raças caprinas e espécies silvestres. As informações foram obtidas através de entrevistas com questionários semiestruturados, complementadas com listas-livres. Foram entrevistados nove criadores, considerados especialistas locais. Foram identificadas 13 espécies selvagens como as principais causadoras de danos para as criações de caprinos da região. As espécies citadas foram carcará (Caracara plancus), gato-mourisco (Puma yagouaroundi), conhecido e designado na região pelos criadores como gato-do-mato azul e vermelho, jiboia (Boa constrictor), urubu (Coragyps atratus), cão doméstico (Canis familiaris), raposa (Cerdocyon thous), cascavel (Crotalus durissus), morcego (Desmodus rotundus), jararaca (Bothropoides erythromelas), onça-parda (Puma concolor) e gavião (espécie não-identificada), em ordem decrescente de importância.  O conflito entre criadores de caprinos e os animais silvestres se deve aos prejuízos econômicos causados pelos ataques. Os criadores diferenciam as espécies predadoras principalmente pela forma e intensidade dos ataques. Em geral, a caça ainda é a principal forma de prevenção dos ataques, porém, registraram-se formas locais de defesa para algumas espécies. É necessário que se estabeleça um diálogo constante entre os criadores e os órgãos ambientais responsáveis pelas políticas públicas com o objetivo de desenvolver estratégias para a conservação das raças locais, como a raça Moxotó, e espécies silvestres.

Dermatophytes are keratinophilic fungi that can cause zoonosis. However, the role wild animals play in the transmission of these infections is yet to be determined. The aim of this study was to determine the presence of dermatophytes on the haircoat of Brazilian wild mammals. Thirty-two healthy wild mammals from several taxa were studied: 17 were captive and 15 were free-living individuals. Samples were obtained by rubbing the haircoat with sterile carpets. Samples were cultured on Mycobiotic agar, and the plates were incubated at 25 ºC. Identification of the isolates was carried out on the basis of macro- and micromorphology. Dermatophytes were isolated from 9.5% of the animals: Microsporum gypseum from one maned wolf (Chrysocyon brachyurus), Microsporum cookie from one coati (Nasua nasua), and Trichophyton ajelloi from one bush dog (Speothos venaticus). These animals represent therefore sources of infection for both humans and other animals and are important for public health policies.

Toxoplasma gondii is an obligate intracellular protozoan parasite, recognized as the etiologic agent of toxoplasmosis, a zoonotic endemic disease in several countries, including Mexico. In the Yucatan State of Mexico, Toxoplasma infection has a high impact in both human and domestic animal health. Wild animals can also host zoonotic pathogens such as Toxoplasma gondii. The presence of Toxoplasma gondii DNA in roadkill wild animals in Yucatan was detected using a nested Polymerase Chain Reaction. Toxoplasma gondii DNA was identified in several organs retrieved from a Yucatan squirrel (Sciurus yucatanensis), a coatimundi (Nasua narica), and a greater grison (Galictis vittata). The amplified fragments of Toxoplasma gondii DNA were purified, sequenced, and certified by BLAST analysis. Our results confirm that Toxoplasma gondii can infect wild mammals from Yucatan, which could act as intermediate hosts and contribute to the transmission of the disease to humans and domestic animals, as well as other wild animal species. We present the first molecular evidence of Toxoplasma gondii in a squirrel and a coatimundi from Yucatan, and quite possibly in a greater grison at a global level.Figure 1.

Trypanosomes are a group of parasitic flagellates with medical and veterinary importance. Despite many species having been described in this genus, little is known about many of them. Here, we report a genetic and morphological characterization of trypanosomatids isolated from wild mammals from the Argentine Chaco region. Parasites were morphologically and ultrastructurally characterized by light microscopy and transmission electron microscopy. Additionally, 18s rRNA and gGAPDH genes were sequenced and analyzed using maximum likelihood and Bayesian inference. Morphological characterization showed clear characteristics associated with the Trypanosoma genus. The genetic characterization demonstrates that the studied isolates have identical sequences and a pairwise identity of 99% with Trypanosoma lainsoni, which belongs to the clade of lizards and snakes/rodents and marsupials. To date, this species had only been found in the Amazon region. Our finding represents the second report of T. lainsoni and the first record for the Chaco region. Furthermore, we ultrastructurally described for the first time the species. Finally, the host range of T. lainsoni was expanded (Leopardus geoffroyi, Carenivora, Felidae; and Calomys sp., Rodentia, Cricetidae), showing a wide host range for this species.
